Abstract
The present invention relates to hair styling compositions and in particular to hair spray compositions. These compositions comprise a silicone containing adhesive copolymer, having a weight average molecular weight from about 10,000 to about 5,000,000, and a solvent for said copolymer selected from the group consisting of water, ethanol, n-propanol, isopropanol, and mixtures thereof. The spray compositions, when dried, have a cohesive strength of greater than about 0.5 kgf/mm.sup.2, a total energy absorption per unit volume of greater than about 0.55 kgfmm/mm.sup.3 and , preferably an impact strength of greater than about 7000 ergs. The hairspray embodiments of the present invention preferably provide improved removeability from hair as defined by a hair stiffness value of from 0 to about 3.5 (0 to 4 scale) and a hair flaking value of from 0 to about 3.5 (0 to 4 scale) as determined by the removeability methodology defined herein. The instant invention also relates to a method of styling and/or holding hair comprising the step of applying to the hair an effective amount of the above compositions.
